Epidemiological evidence suggests that the increased incidence of a variety of human cancers, such as lymphoma, leukemia and liver and breast cancers, might be attributed to exposure to these agents.
How chlorinated hydrocarbons have a negative impact on plants?
Which of the following best explains how chlorinated hydrocarbons have a negative impact on plants?
They bond and accumulate on the plant
.
How do chlorinated hydrocarbons impact the human body?
Based on toxicology, metabolism, animal studies, and human studies, occupational exposure to chlorinated aliphatic solvents (methanes, ethanes, and ethenes) has been associated with numerous adverse health effects, including
central nervous system, reproductive, liver, and kidney toxicity, and carcinogenicity
.
Which is the most toxic of the chlorinated hydrocarbons?
Dieldrin
is not a registered pesticide in the USA. Residues limit its application, and it is one of the most toxic chlorinated hydrocarbon insecticides.
What do chlorinated hydrocarbons cause?
Many
chlorinated
solvents are considered potential carcinogens and some, such as TCE and PCE, may degrade in anaerobic groundwaters to produce more toxic substances such as vinyl chloride.
What caused chlorinated hydrocarbons to be banned?
Chlorinated hydrocarbon insecticides are highly soluble in fats and oils. ... Most of these insecticides have been banned or restricted in the United States
because of their persistence in the food chain
, which leads to deleterious effects on wildlife.
What is an example of a chlorinated hydrocarbon?
The chlorinated hydrocarbons were developed beginning in the 1940s after the discovery (1939) of the insecticidal properties of DDT. Other examples of this series are
BHC, lindane, Chlorobenzilate, methoxychlor
, and the cyclodienes (which include aldrin, dieldrin, chlordane, heptachlor, and endrin).
Are organochlorines still used?
Organochlorine pesticides are chlorinated hydrocarbons used extensively from the 1940s through the 1960s in
agriculture and mosquito control
. ... As neurotoxicants, many organochlorine pesticides were banned in the United States, although a few are still registered for use in this country.
What are chlorinated pesticides?
Chlorinated pesticides are
a small but diverse group of artificially produced chemicals characterized by a cyclic structure and a variable number of chlorine atoms
. Most members of the group are resistant to environmental degradation and relatively inert toward acids, bases, oxidation, reduction, and heat.
What are the health effects of chlorinated solvents?
Short-term side effects may include
dizziness, fatigue, headaches, and/or skin rashes
. Long-term side effects may include chronic skin problems, and/or damage to the nervous system, kidneys, or liver. Some chlorinated solvents are also known to cause cancer, in both humans and animals.
Can chlorinated hydrocarbons be absorbed through the skin?
Chlorinated hydrocarbon insecticides are highly lipid-soluble and are
readily absorbed through the skin
and across mucous membranes, although they are not particularly volatile and therefore inhalation is not an important route of exposure.
Which chemical is called chlorinated hydrocarbons?
Chlorinated hydrocarbon (CHC) is a generic term given to
compounds containing chlorine, carbon and hydrogen
. The term can be used to describe organochlorine pesticides such as lindane and DDT, industrial chemicals such as polychlorinated biphenyls (PCB), and chlorine waste products such as dioxins and furans.
Is chlorinated hydrocarbon a neurotoxin?
Chlorinated hydrocarbons are
neurotoxins
that interfere with transmission of nerve impulses, especially in the brain, resulting in behavioral changes, involuntary muscle activity, and depression of the respiratory center. ... In addition, some chlorinated hydrocarbons may be carcinogenic.
Is bleach a chlorinated hydrocarbon?
Probably the most important use of chlorine is as a water purifier. ... Ordinary laundry bleach is a 5.25% solution of sodium hypochlorite in water. Among the important organic compounds containing chlorine are the
chlorinated hydrocarbons-hydrocarbons
that have had some of their hydrogen atoms replaced by chlorine atoms.
Are chlorinated hydrocarbons naturally occurring?
We rarely think of thousands of chlorinated hydrocarbons that exist in the natural systems, several of which are highly
toxic
to humans (1). ... Researchers have also shown that some chlorinated compounds, previously considered to be from anthropogenic sources, are also produced by microbial processes in soil systems (6).
