Air pollution in large cities has been a major and a serious environmental problem all over the world; hence, many countries initiated air quality management systems to monitor and control pollution rates around big cities. It was found that harmful emission into the air is a symbol for environmental force that affects seriously man’s health, natural life and agriculture; thus leading to major ...
Brucellae infections have been documented world-wide over the years in a great variety of terrestrial wildlife species. Recently, brucellae infections have also been reported in a wide variety of marine mammals. A very important consideration with regard to terrestrial brucellosis in wildlife is to distinguish between a spillover of infection from domestic animals and a sustainable infection in...
The existing empirical literature on farmers’ use of soil-conserving, runoff-reducing farming practices, while sizable, contains relatively little information on the influence of cost on adoption decisions and on how farmers combine multiple practices into an overall conservation package. Such knowledge is important in light of current interest in reorienting agricultural policy toward environm...
Antimicrobial resistance is a growing public health challenge worldwide, with agricultural use of antimicrobials being one major contributor to the emergence and dissemination of antimicrobial resistance (AMR). Globally, most antimicrobials are used in industrial food animal production, a major context for microbiomes encountering low-doses or subtherapeutic-levels of antimicrobial agents from ...
The objective of study is to provide an analysis of data trends on the type of pesticide used, exposure factors, and the pesticide-related concerns among the farmers from 2005 to 2010 in one of the largest vegetable producing areas in the Philippines. This is to determine and analyze changes that have occurred for the last five years in order to provide necessary basis in promoting safe usage o...
In the recent years, agricultural soils have received more chemicals in various forms for higher yields. This may result in the accumulation of metals in soils which subsequently may be transferred into the agricultural crops. In the present investigation, nickel content of 58 composite soil samples and also agricultural crops, is studied. Ni in samples of soil and agricultural products were ex...
/ Maryland, Virginia, and Pennsylvania, USA, have agreed to reduce nutrient loadings to Chesapeake Bay by 40% by the year 2000. This requires control of nonpoint sources of nutrients, much of which comes from agriculture. Riparian forest buffer systems (RFBS) provide effective control of nonpoint source (NPS) pollution in some types of agricultural watersheds. Control of NPS pollution is depend...
background & aims of the study: in this research, long-term hydrologic impact assessment model is selected for simulation of runoff and nps pollution. the aim of this study is modeling of non-point source pollution by l-thia model in zayandehrood watershed in 2015. materials & methods: in this study, analytical survey and investigation of references in the context of library studies has been us...
Environmental pollution is one of the serious crisis to which we are facing today. It is fact that three basic elements air, water and land which constitute harmony of nature for proper and balance living of all organisms, it was fortunate enough that such hospitable and balance environment was the destiny of our predecessors. But it is contrary to living of the present environment. With the ra...
