Abstract: This paper examines the sanitary-risk factors in relation to some hand-dug wells in Zaria city of Kaduna State. Ten (10) wells were randomly selected from city-wards and field inspections of the wells were conducted in each selected ward. The simple percentage was carried out for analysis of data. The results indicated that 80 percent of the wells were within 10m of latrines, while 70 percent of the wells were very close to a source of pollution at about 10m radius. The study recommended that vigorous environmental education programmes should be embarked upon to public on a proper ethics of citing wells. There should be sanitary inspection of the source of water as a routine activity.

Abstract: Effect of urban air pollution on roadside tree species Pongamia pinnata(L.) Merr. has been studied with special reference to epidermal characteristics of leaves. The light microscopic studies of this plant indicated marked alteration in epidermal traits, with increased number of stomata and epidermal cells per unit area in leaf samples collected from polluted sites than those from control site. Results revealed that, as compared to the leaves from control, the length and width of guard and epidermal cells reduced considerably in leaves of polluted sites. These changes in epidermal traits could be as indicator of environmental stress and can be recommended in high traffic density area for the early detection of urban air pollution.
Keywords: Urban air pollution, epidermal cells, stomata.

Abstract: Pesticides have an innate capacity to cause damage to biological system. Considering above fact the present study deals with the effect of the insecticide malathion on histological and biochemical study on cardiac muscle tissue in Channa punctatus. In present study effect of sub lethal concentration (0.8 ppm) of malathion on protein, lipid and glycogen content and histopathological changes in heart tissue of fresh water fish Channa punctatus during 96 hours was studied. Structural variations like congestion, atrophy were observed in cardiac muscle of Channa puncctatus during 96 hours sub lethal treatment of malathion. Total protein, lipid and glycogen showed decrement in cardiac muscle of Channa punctatus
Keywords: Malathion, sub lethal, cardiac muscle, Channa punctatus

Abstract: The word Arsenic is always alarming to us. It is nothing but a prejudiced view. If we take arsenic through drinking water or in other forms, it is not always injurious to health. It is a matter of lookout weather its intake is within or beyond the danger level. All of us should be aware of the value of danger level. The present study deals with to create consciousness among the people in respect of danger level of arsenic in drinking water. The sample consist of 50(N=50) Tube Wells of different families gathered by Situational Sampling Technique from different rural areas of Habra Block, North 24 Parganas, West Bengal, India. The findings reveals that a large portion of the areas of North 24 Parganas, is dominated by arsenic pollution and people suffer from arsenic-stricken diseases because of their ignorance and lack of awareness regarding arsenic pollution and its impact on Human Health. Some remedial measures should be taken to generate awareness among general people from government, semi-government organizations, NGOs and other individual and collective efforts. Further studies are necessary in this regard.
