• Some foods, including:
  • Seafood, especially shellfish. The form of arsenic in seafood is not considered to be a health concern.
  • Rice and foods with rice-based ingredients, such as some hot and cold cereals, some infant formulas, and rice cakes. Rice plants can take up arsenic from water or soil.
  • Hijiki seaweed (short, black, noodle-like seaweed).
• Drinking water sources in some places, such as parts of the Central Valley and some areas in Southern California.
• Some pressure-treated wood used in outdoor structures, such as decks and playground equipment. Arsenic-treated wood was phased out in 2004.
• Cigarette and other tobacco smoke.
• Some herbal medicines and other traditional remedies, especially from China and India.
• Some herbicides in limited use at golf courses, cotton farms, and sod-growing facilities.

• May harm the developing fetus.
• May harm the nervous system and affect learning in children.
• May contribute to cardiovascular disease and affect lung function.
• Can increase cancer risk.

• Include plenty of variety in your and your child’s diet.
• If you have an infant, breastfeed if you can. Include alternatives to rice-based foods in your infant’s diet.
• Do not burn older pressure-treated wood (manufactured before 2004), and avoid using it for home projects.
• Have children wash their hands after they play on or around older wooden play structures or decks. If you own such a structure or deck, apply a sealant or coating every one to two years.
• Because arsenic can collect in dust:
  • Wash your and your child’s hands often, especially before preparing or eating food.
  • Clean your floors regularly, using a wet mop or HEPA vacuum if possible, and use a damp cloth to dust.
• If your water comes from a private well, have it tested for metals, including arsenic. (If your water comes from a public water supplier, it is already tested regularly for arsenic.)

• Commercial disinfectants used in hospitals, nursing homes, schools, veterinary clinics, barber shops, agricultural operations, and other industries.
• Other items, such as:
  • • Some paints, adhesives, leather, and textiles, as a preservative.
    • Some beverage cans.
    • The surface of some citrus fruits and pears, in small amounts from agricultural fungicide application.
    • Some freshly cut wood treated for fungus.
    • A few household pest control products with added disinfectant.
    • A few personal care products, such as cleanser for sensitive skin.

• Might have an effect on the body’s natural hormones.
• May increase cancer risk.

The use of o-phenylphenol has been declining and exposures for most people are expected to be very low.  If you think you might be exposed to o-phenylphenol in the ways listed above, here are some actions you can take:

• Wash your hands regularly, especially before eating or preparing food.
• Wash all citrus fruit and pears before eating.
• Clean your floors regularly and use a damp cloth to dust, because o-phenylphenol might be found in dust.

• Polyurethane foam in a variety of products, including:
  • Upholstered furniture in homes and offices.
  • Some car seats for infants and children.
  • Motor vehicle seats, carpet padding, and foam blocks at gymnastic studios.
• Some building materials, such as insulation and plastic pipes.
• Some fabrics used in curtains, costumes, and camping tents.
• Some children’s products made from plastic, foam, or synthetic rubber, such as soft toys and arts and crafts supplies.
• Paints, varnishes, and adhesives.
• Dust in homes, offices, and cars that contain products with these flame retardants.

Scientists are still studying how chlorinated phosphate flame retardants may affect people’s health.  Some chlorinated phosphates:

• May interfere with the body’s natural hormones.
• May decrease fertility.
• May affect the developing fetus.
• May increase cancer risk.

• Because these flame retardants can come out of products and collect in dust:
  • Wash your and your child’s hands often, especially before preparing or eating food.
  • Clean your floors regularly, using a wet mop or HEPA vacuum cleaner if possible, and use a damp cloth to dust.
• Look for furniture that has “TB117-2013” labels, the new California flammability standard that can be met without using chemical flame retardants.  The label should indicate if the furniture contains flame retardants or not.
• Avoid new and used furniture with “TB-117” labels, which is more likely to contain chemical flame retardants. 
• Ask for children’s products that do not contain flame retardants. Contact the manufacturer if the seller is unsure whether a product contains flame retardants.
• Replace upholstered furniture that is torn or has crumbling foam.
• If you install new carpet, avoid using padding made from recycled or scrap foam.

Weed control products used in the past in forests, parks, pastures, lawns and along roadsides and railroad tracks. All uses of 2,4,5‐T in the U.S. ended by 1985.

Weed control products that contained 2,4,5‐T were contaminated with dioxin, a toxic chemical known to cause cancer and harm the developing fetus. Use of these weed
control products ended because of toxicity concerns, but it is not known whether 2,4,5‐T itself posed health concerns or if toxicity was due to dioxin alone.

No actions are suggested because 2,4,5‐T is no longer used and does not last a long time in the environment.

• Some home lawn products labeled as weed killers and for “weed and feed” use.
• Commercial weed control products used along roadsides and railroad tracks, and in recreational areas such as golf courses, athletic fields, and parks.
• Some herbicides for crops such as wheat, almonds, and some citrus and stone fruits.

Scientists are still studying how 2,4-D might affect people’s health.  There is concern that 2,4-D:

• May interfere with the body’s natural hormones.
• May harm the developing fetus.
• May increase cancer risk.

• Use non-chemical methods to control weeds, such as regular mowing and hand-weeding.
• If you choose to use a weed killer, spot-treat problem areas and follow warning statements on the label.  After application:
  • Remove shoes before entering your house; remove clothes that are soiled during application and launder them separately.
  • Limit access to 2,4-D treated areas, at least until the product has completely dried; for children and pets, limit access for one to two days or longer if possible.
  • Look for posted notices that indicate an area (such as a park or athletic field) has been treated with a weed killer and follow any precautions on the notice.

• Rubber products, like tires.
• Recycled rubber products, including artificial turf for athletic fields and playgrounds and rubber gardening mulch.
• Some detergents, adhesives, inks, paints, and varnishes.

Scientists are still studying how 4-t-octylphenol may affect people’s health.  There is concern that 4-t-octylphenol:

• May interfere with the body’s natural hormones.
• May affect the reproductive system.

• Based on studies conducted so far, exposure to 4-t-octylphenol is expected to be very low for most people.
• No actions are suggested to reduce exposure.

• Diesel exhaust, which is the most common source of 1-NP.
• Other sources include:
  • Exhaust from engines that burn biodiesel, a plant-based alternative to diesel fuel.
  • Exhaust from gas burners and kerosene heaters.
  • Smoke, such as from burning cooking oil, grills, or wood fires.
  • Food that has been grilled, barbecued, or smoked, and some teas.
  • Secondhand tobacco smoke.

• 1-NP may increase cancer risk.

• The main way to reduce your exposure to 1-NP is to reduce your exposure to diesel exhaust; please refer to our fact sheet on Diesel Exhaust for more information.
• Possible ways to reduce your exposure to 1-NP from sources other than diesel exhaust and improve indoor air quality include:
  • Always use an exhaust fan when cooking indoors with an oven, stovetop, gas burner, or hot plate. If you do not have an exhaust fan, open your windows when you cook, and use a portable fan to help move the air outside.
  • Do not use a gas oven or gas burners to heat your home.
  • If you cook with barbecues or grills, use them outdoors only.
  • Do not smoke or allow others to smoke in your home or car, or around your child.
• Limit how much you eat grilled, barbecued, smoked, fried, or roasted food. Avoid burning food. Try steaming, boiling, stewing, or poaching your food more often.
• Because 1-NP and other chemicals can collect in dust:
  • Wash your and your child’s hands often, especially before preparing or eating food.
  • Clean your floors regularly, using a wet mop or HEPA vacuum cleaner if possible, and use a damp cloth to dust.

• Cosmetics and personal care products, including some:
  • Make-up, such as mascara, eye shadow, lipstick, and foundation.
  • Facial cleansers and scrubs.
  • Moisturizers, lotions, and sunscreens.
  • Shampoos, conditioners, and shaving creams.
• Baby products, such as some lotions, baby wipes, and diaper rash ointments.
• Some over-the-counter and prescription medications.
• Some household products, such as some stain removers and pet shampoos.

Scientists are still studying how parabens might affect people’s health.  There is concern that some parabens:

• May interfere with the body’s natural hormones.
• May decrease fertility.

• Consider choosing cosmetics, personal care products, and baby products that use natural preservatives, such as vitamin C (might have words like “ascorbate” or “ascorbic” on the label).
• Try natural oils for skin and hair, such as coconut oil, olive oil, and sunflower seed oil.
• For infants, consider using plain washcloths instead of baby wipes, and wash their skin with ordinary soap and water.

• Certain foods, such as nuts, grains, beans, and leafy green vegetables.
• Some drinking water sources.
• Certain metal alloys, such as steel.
• Some welding rods.

• Some manganese is needed to support many important processes in the body, such as building bones and healing wounds.

Too much manganese:

• May be associated with learning and behavior problems in children.
• Can harm memory, thinking, mood, and balance in adults.

• Eat a well-balanced diet with adequate iron, which can help you maintain a healthy level of manganese.
• If you do any welding or metalworking, be sure that your work area is well ventilated and use proper protective equipment.
• Keep children away from welding fumes and other metal vapors and dusts.

• On-road vehicles that run on diesel fuel, such as semi-trailer trucks, light-duty trucks, and some buses and passenger cars.
• Diesel-powered freight and passenger trains, and cargo and cruise ships.
• Heavy-duty equipment, such as bulldozers and tractors, used for construction, agriculture, landscaping, mining, and similar types of work.
• Diesel-powered generators.

• Can make asthma worse and contribute to other respiratory diseases, like chronic obstructive pulmonary disease (COPD).
• May harm the lungs and lower resistance to respiratory infections.
• May make allergic reactions to dust, pollen, and other allergens worse.
• Can make existing heart conditions worse.
• Can increase cancer risk.

• When walking, riding a bike, or exercising outdoors, choose areas away from roadways whenever possible, or side streets with less traffic. Avoid busy highways and paths near train routes.
• When in heavy traffic, keep vehicle windows closed and put the air on recirculate (look for this symbol or check your manual:  ).

• Always start and operate diesel engines in a well-ventilated area.
• If you have a diesel car or truck, don’t idle inside garages, especially garages attached to your home.
• If you have a backup or portable diesel-powered generator, put it well away from your home, to make sure that exhaust does not come in through open windows or doors.
• If possible, use a high-efficiency filter in your home’s central heating and air system.
• Consider buying a portable air cleaner (or “air purifier”) that can remove small particles from the air in your home (see below).
• Because chemicals from diesel exhaust can collect in dust:
  • Wash your and your child’s hands often, especially before preparing or eating food.
  • Clean your floors regularly, using a wet mop or HEPA vacuum cleaner if possible, and use a damp cloth to dust.
• Report diesel trucks in California if they are:
  • Idling where “No idling” signs are posted, or idling for more than five minutes.
  • Not following designated truck routes.
