Abstract

Solid waste management poses crisis in many of the world's large urban areas due to explosive population growth and massive shift of population towards urban. Keeping in mind of the above problem a study has been done to find out the possible sources and the nature of solid wastes generated at different places of Burdwan town, West Bengal. Moreover, a questionnaire was made and was applied the same to the locality adjacent to the dumping centers. It was found that solid wastes mainly are polythene packets, plastic bottles, glass bottles, papers, coal ash, cottons, bandages, injection syringes, jute packets, needles, sands, torn cloths, torn mats, torn sacks, clay pots, scales of fish, rotten vegetable etc. The physicochemical parameter of the solid wastes viz. pH, phosphate, moisture, potassium, organic matter, organic carbon, nitrogen were assessed. The C/N ratio are 7.66-8.41; 0.029- 0.144,21.88-40.67; 0.54-0.67; 6.311-10.976; 3.406-7.011; 0.57 and 5.01-10.11 respectively. The pH of drinking water collected from different distance viz. (5 m, 10 m, 15 m, 20 m) from dumping centers does not show significant difference and ranged between 6.5-6.8.

Abstract

Fluoride is a chemical element that has shown to cause significant effects on human health and plant body. Fluoride has been known to be found most frequently in groundwater at higher concentrations, depending on the nature of rocks and natural -carrying minerals at certain depths. This paper basically discusses how and what manner fluoride pollute the air, underground water and soil and subsequently which species of fluoride are responsible for pollution in animal and plants and finally some traditional techniques (Acivated alumina. Reverse osmosis. Ion exchange and Electro dialysis reversal etc.) for fluoride removal from drinking water.

Keywords

Fluoride, Groundwater, Air, Soil Removal Techniques, Nalgonda Techniques.

Abstract

Present article demonstrated the origin and toxic nature of arsenic in both animal and plant body. Study results also focused on the accumulation pattern of arsenic in different vegetables, soil and water. Finally it was suggested few house-hold and low-cost technology for removal of such toxic element from drinking water.

Keywords

Arsenic, Accumulation, Vegetable, Soil, Water, Low-Cost Technology.

Abstract

A comparative study of body weight and schoolbag weight of six year old children of Elnglish medium and Bengali medium schools was done in Burdwan town. The result revealed that average bag weight carried by English medium children and Bengali medium children are 3.75 kg and 2.16 kg which is equivalent to 18% and 10.8% of their total body weight respectively.
