Data of the Federal Information Fund for Social Hygiene Monitoring conducted on the basis of the Federal Center for Hygiene and Epidemiology of Rospotrebnadzor have been analyzed to assess environmental risks, as well as to develop environmental safety system as a factor for sustainable development of the territory in the regions of the Russian Federation. Atmospheric air pollution in Russian regions was evaluated by content of priority pollutants. Ranking of Russian regions according to the quality of drinking water supply was carried out. The possibility of using Federal Information Fund for Social Hygiene Monitoring as an integral part of the model for optimizing the social and environmental conditions of populated areas is estimated.

Past evaluations of the success of wastewater treatment and submarine outfall placement and operation have considered only a limited number of parameters affecting the marine and onshore environments. Important questions regarding the best allocation of available funds have not been adequately addressed. The relative contamination of the sea from airborne and landwash contaminants has not been considered. Neither has the increased air pollution deriving from the energy required for advanced treatment. Similarly, regular epidemiological studies to evaluate actual changes in morbidity arising from drastic changes in treatment and disposal have not been made prior to very large committments of funds. Most importantly, little attention has been given to the relative ranking of all environmental risks within a catchment area. The net result is that, when all factors are considered, the very large expenditures and increased energy use for sanitary wastewater treatment and outfall disposal will have a net negative effect on the physical and societal environment. The City of Los Angeles and the Los Angeles Metropolitan area can be used to illustrate this probability.

Development of oil palm plantation on peatland was faced with hydrophobicity problem caused by over drained. Hydrophobicity could reduce water retention and nutrient availability in the peat soil. Beside of proper water management application, addition of soil ameliorant which contain iron could increase stability and improve peat soil fertility. The study was conducted to obtain the effect of steel slag on peat soil properties and hydrophobicity. In this study, peat soil was incorporated with steel slag and incubated in 60 days period. The research was employed completely randomized design (CRD) factorial 2 x 2 x 4. First factor is peat maturity consists of two levels: sapric (S) and hemic (H), while the second factor is soil moisture which also consist of two levels: field capacity (W1) and dry (under the critical water content) (W2). The third factor is steel slag dosage which consist of four levels: 0 g pot (TB0), 7.17 g pot (TB1), 14.81 g -1 -1 pot (TB2), and 22.44 g pot (TB3). The result showed that application of steel slag significantly increase of soil pH, ash content, and water retention at pF 4.2. Furthermore, application of steel slag significantly reduce time for water reabsorption (wettability) in sapric. On the other hand, there are negative corellation between water penetration and soil pH, ash content, and water retention at pF 4.2. Overall, application of steel slag could increase wettability and prevent peat soil hydrophobicity.
