ANS.
A & B . There is no direct or particular source for gases like methane and carbon dioxide, they
are the product of various chemical and biological reactions that occur in a land fill. These gases
compose approximately 90 % of gases in a landfill. As for there harmful effects there are many
for e.g. there is concern of global warming , they causes nausea, fatigue at a high concentration
to humans, methane is flammable.
C. Solvents : These can be various chemicals from industrial disposal or domestic disposal also.
These becomes a concern because they tend to seep through the soil and if reaches ground water,
then they can directly pollute it and which may cause various health problems.
D. Organic Nitrogen: Source is mostly sewage or agricultural waste. Organic nitrogen is of
concern as it tends to stimulate and maintain microbial activities in landfills which may increase
total biomass and creating a swampy area which will cause more emission of harmful gases.
E. Rodents: Rodents are the species that survive in landfills, they survive on waste or potentially
hazardous matter present there, which can cause a serious impact on food chain from
environment point of view. Bio-magnification and bio-accumulation are also some serious
problems that can arise from this.
