Primary Sources of exposure |
PCBs |
48 of 73 |
9 of 9 |
57,290 to 455,790 |
pg/g in blood lipid basis |
PCBs, banned in 1976, were used in adhesives,
carbonless reproducing paper, cutting oils, dedusting agents, electrical
capacitors, electrical transformers, vacuum pumps, gas-transmission turbines,
fire retardants, hydraulic fluid, ink, lubricants, pesticide extenders,
plasticizer, heat transfer systems, wax extenders |
Contamination in seafood, meat and dairy products. |
Dioxin-like PCBs |
5 of 12 |
9 of 9 |
1.5 to 10.9 |
pg/g TEQ in blood lipid basis |
Dioxins and furans |
15 of 17 |
9 of 9 |
15.7 to 36.6 |
pg/g TEQ in blood lipid basis |
There are no industrial uses of dioxins or furans. Dioxins and furans are pollution from incineration, chlorine bleaching, PVC plastic production, and other industrial processes. |
Contamination in seafood, meat and dairy products. |
Organophosphate pesticide metabolites |
7 of 9 |
9 of 9 |
4.0 to 70.4 |
ug/L in urine |
Organophosphate pesticides are used as fungicides, herbicides,
insecticides and termiticides. |
Contamination in fruits, vegetables, dairy, and meat products;
Direct exposure from home use |
Organochlorine pesticides and metabolites |
10 of 23 |
9 of 9 |
615 to 3084 |
pg/g in blood lipid basis |
Organochlorine pesticides are used as fungicides, insecticides
and termiticides. |
Contamination in fruits, vegetables, dairy, and meat products;
Direct exposure from mosquito control spraying prior to the 1970s |
Phthalates |
6 of 6 |
9 of 9 |
97.2 to 904.8
[only Bis (2-ethylhexyl) phthalate was quantified] |
ug/g in blood lipid basis * |
Phthalates are used as plasticizers, solvents, desensitizing
agents, dye carriers, perfume fixatives, and defoaming agents, as well as
in nail polishes and explosives. |
Exposure occurs upon contact or consumption of plastics, cosmetics,
contaminated food, carpet, explosives, sealants, varnishes, paints, and
primers |
Other semivolatile and volatile chemicals (24 classes) |
77 |
9 of 9 |
not quantified |
|
The SVOCs and VOCs found in these 9 people are used in products
from aviation fuel to food flavorings. |
Daily life: exposures may occur from contaminated food, paints,
furniture, or any number of other common consumer products |
Metals |
4 of 5 |
|
(see below) |
Lead |
|
9 of 9 |
1.01 to 3.23 |
ug/dL in whole blood |
Lead is released as pollution from burning fossil fuels, mining
and manufacturing. Lead is used in ammunition, aviation fuel, batteries,
cables, x-ray shields, and ceramics. Lead has also been historically used
in paint, crystal tableware, gasoline, and drinking water pipes. |
Chipping paint in older homes and water from lead pipes or
lead solder in homes built before 1986 |
Methylmercury |
|
7 of 9 |
0.63 to 25.9 |
ug/L in whole blood |
Methylmercury is created in the environment by bacteria converting
mercury pollution, especially mercury from coal-fired power plants. |
Canned tuna and other seafood that accumulates methylmercury
from the environment |
Arsenic, inorganic |
|
1 of 9 |
21 |
ug/L in urine |
Arsenic is used in pressure-treated lumber, alloying constituents,
certain types of glass, doping agents in germanium and silicon solid state
products, dipoles and other electronic devices, copper and lead alloys,
and even medicines. |
Contact with outdoor lumber decks and playsets treated with
Chromated Copper Arsenate (CCA); Contaminated drinking water |
Cadmium |
|
3 of 9 |
0.5 to 0.7 |
ug/L in urine |
Cadmium is released as pollution from mining and industrial
operations and coal or waste combustion. Cadmium is used in baking enamels,
batteries (Ni-Cd), electronics, fire protection systems, industrial machinery,
lithography, machinery enamel, marine equipment, optics, pigments, nuclear
reactor control rods, electroplating for automotive, aircraft & electronic
parts, and to manufacture fungicides. |
Foods contaminated with cadmium (shellfish, and some organ
meats); Contaminated air near coal or waste combustion plants |
