limit value, control measures. Different physical agents & their Protective
measures. Noise as a potential industrial health hazard. Thermal stress & its
effect & control measures. Chemical agents IS/UN classification,
flammables, explosives, water sensitive chemicals, oxidants, gases under
pressure, chemicals causing health hazards: irritants, Axphyxiantes,
Anaesthetices, systemic Poison and carcinogens, Types of air borne
contaminant, occupational exposure limits, control measures, principals of
ventilation.
* Current development in the subject:-
Env. 502 : Environmental Toxicology and Hazardous Waste
Management:-
Unit-I :- Scope and concepts of ecotoxicology and toxicology,
paracelsus’s view of poison; clinical, environmental, economic
toxicology; xenobiotic concentration and dose, calibration of Dose
response curve, lethal, Lc50 and threshold concentration, acute, sub
acute and chronic toxicity; bioconcentration and biomagnifications,
Toxicity Vs chemotherapy. Neurothxicity, carinogenicity, &
mutagenecity.
Unit II :- Bio-assay techniques; study design protocols to evaluation of
toxicants. Tests for assessing carcinogenicity and muta toxicity of
compounds. TLC techniques for determination of toxicants in water &
vegetable samples.
Unit III :- Classification of toxicants: natural and synthetic toxins;
chemicals classification and mode of action of pesticides. Recent trends
in the use of pesticides. Plant toxins; Afflotoxins, ergots, pyrethriods.
Heavy metal pollution caused by lead, arsenic, mercury , cadmium and
chromium, their effect on human health. Factors affecting metabolism
of xenobioties.
