ammonium is due to bacterial action on nitrogen compounds in the soil and biomass
burning, together. The non sea salt (nss) fraction analyses suggest that the contribution
of nss- SO 4 -- is 94%. The acidic pollutants, such as sulphate and nitrate are derived by
long distance transport, local industrial as well as traffic sources. The major sources of
nitrate in this area are emissions of oxides of nitrogen from automobiles, biomass
burning and soil. The results of this study suggest that the rainwater chemistry is
strongly influenced by local pollution as well as anthropogenic sources.

Strong evidences have emerged that food and environment are major causes of
cancer in human population. Dioxins emitted from various industrial processes and
diesel combustion are proven human carcinogen, as per USEPA and ICRA. A case
study of dioxin release from auto-rickshaws, crude diesel generators, municipal waste
burning and industrial combustion was done in Yamuna Nagar district, Haryana. There
is a regular incomplete combustion of 69,131,00 liters or 5599 Metric Tons (MT) of
Diesel, annually, by Auto-Rickshaws & unapproved crude diesel generators used by the
public and 15,330 MT of solid wastes burning every year, releasing total dioxin
emission more than 370 MT in the environment. Dioxin is such a dangerous carcinogen
that 0.1 microgram per liter of air causes 10 cancer cases. What is more important that
while smoke released by Industries is released above 30 feet but the smoke containing
dioxin released by auto-rickshaws, unapproved diesel generators, and municipal waste
burning in open remains at lowest strata upto 10 feet where human population breathes
more, thus inhaling even higher doses of dioxin per day. Out of approximate 400 cancer
cases in the district, 209 cases are estimated to be due to dioxins alone! This district
model of dioxin related carcinogenesis could be well extended to other cities as well.
The policy makers and pollution law enforcing agencies need to swing into action for
absolute curb on emission of dreaded dioxin in the environment. They need to realize
that they also breath the same dioxin contaminated air that their fellow countrymen
breath.
