The objectives of this study were to examine the carbon sequestration dynamics under different age Casuarina plantation at Sagar Island, West Bengal. The organic carbon content in surface and sub-surface soil ranged from 25.8-58.8 and 12.1-25.7 tonn/hectare, respectively. Soil organic carbon under old Casuarina showed 15 times more value than the unplanted soil of the Sand Dunes. Rate of carbon sequestration was observed to be the maximum (4.3 tonn/year) under new Casuarina plantation near to the tree.

Results showed that 316 water samples were non-potable and 109 potable by MPN and 95% correlation at 37°C was recorded after 18 hr of incubation by H₂S test. When MPN index >10, H₂S test at RT was 16%, 33%, and 65% correlative, while at 37°C it was 35%, 44% and 64% correlative with MPN test after 18 hr, 24 hr and 48 hr of incubation, respectively. H₂S test showed 98% and 71% correlation with Eijkman test and membrane filter technique. Study showed that H₂S test showed maximum correlation at 37°C after 24 hr to 48 hr of incubation as compared to room temperature, when compared with standard technique for detection of fecal contamination in drinking water. Thus concluded that the H₂S test could be used to screen water for fecal contamination in the field where laboratory facilities are limited.

The crop was sown on 20th November 2011 (normal sown) and 20 December 2011 (late sown). On the basis of observations recorded it was concluded that genotypes IC-536265 and IC-443729 for earliness, IC-443729 and IC-445595 contain high chlorophyll, IC 116274 for low canopy temperature, IC 565811 for high membrane stability, IC 443727 maintains high relative water content and IC 290230 for high seed protein, while biomass and seed yield/plant were more in IC-75242 and IC-128167 under late planting condition showing tolerance to terminal heat tolerance. Therefore, accessions showing higher values of the above traits could be used in breeding programme for improving tolerance to terminal heat.

At ambient temperature, bitumen is solid and does not present any health/environmental risk. According to the literature survey, the vapours of bitumen contain pungent odour. This is mainly because the bitumen has small amount of poly-aromatic hydrocarbons, and along with some other volatiles like benzene, toluene, etc., which are known to be carcinogenic in nature. In 2001, epidemiological study by IARC (International Cancer Research Agency) was proved that the deaths due to lung cancer are more intense than the other type of cancers. According to recent study, the effect of bitumen fumes caine eye and respiratory tract inflammation, headache, fatigue, lethargy, loss of appetite etc. Due to various applications in the use of hot asphalt released small amount of polyaromatic hydrocarbon should influence health and environment. Safety procedures are very much useful for prevention from the danger of bitumen fumes. In the present study, the health and environment impact of emissions from hot bitumen used during in various techniques, characteristics of released fume and minimized by safety practice are explained.
