The environmental quality is an important factor to ensure the safety of agricultural products. The agricultural products belong to the agro-ecosystem, also affected by various systems. Climate and meteorology (precipitation, light, heat and temperature) are objective factors that affect agricultural productivity, but can’t be evaluated in laboratories. Therefore, generally, factors such as air, water and soil, are environmental quality assessment indicators for agricultural products.
As an analytical testing company with extensive experience in environment of producing area testing, Alfa Chemistry can provide incredible services and credible testing results for our clients.
Environment of producing area testing services provided by Alfa Chemistry:
➢ Farmland Irrigation Water
Sewage irrigation is an effective measure to comprehensively utilize water and fertilizer resources. It plays a good role in promoting agricultural production and reducing agricultural costs. However, some industrial wastewaters, especially some industrial waste waters, often contain a large number of toxic pollutants, such as mercury, cadmium and other toxic heavy metals, which are harmful to humans and animals, so that agricultural products do not meet the hygienic standards of food and feed. If wastewater is not treated and improperly irrigated into farmland, it will inevitably harm crops, affect crop yields, and directly cause economic losses in agricultural production.
➢ Livestock and Poultry Drinking Water
Water is one of the best vectors for pathogenic microorganisms or harmful microorganisms. However, pathogens spread by water are easily overlooked. The pollution of livestock drinking water will lead to multiple hazards, such as inducing diseases, reducing feed conversion rate and drug effects, decreasing production performance of livestock and poultry and resulting in food safety issues.
Soil is one of the main natural resources for human survival and development, and an important part of human ecological environment. However, today's soil environment and food safety has become a hot topic that has a wide and far-reaching impact. Due to the rapid development of modern industry and agriculture, environmental pollution has become increasingly serious. Industrial and mining enterprises dump and stack solid waste into the soil. Road waste, urban sewage, industrial wastewater, and atmospheric sediment enter the soil, constantly deteriorate the soil pollution situation and decreases soil quality. Soil crops are seriously endangered, and food quality continues to decline and affect human health.
Common pollutants in the soil include heavy metal pollution, pesticide pollution, fluoride pollution, soot dust, metal fly ash, acid rain, polychlorinated biphenyls, phenolic pollutants, etc.
The quality of the atmospheric environment is closely related to the growth of plants, and crops are especially more susceptible to the quality of the atmospheric environment. Firstly, because crops have a large leaf area for photosynthesis and gas exchange with the air, some pollutants will affect the photosynthesis and respiration with gas exchange; secondly, they can hardly buffer the adverse effects of external environmental changes; finally, plant locations are generally fixed, unlike animals that can avoid open-air pollution through action. When the content of certain pollutants in the atmosphere exceeds normal levels for a long time, it will not only cause adverse impacts and harms on crops, fruit trees and vegetables, cash crops and green plants, but also bring huge economic losses to people. The main types of atmospheric pollutants and the hazards to crops are currently noted or have a greater impact on the ecological environment, and there are about 100 kinds of atmospheric pollutants with a large discharge that pose a greater threat to human health. Among them, the main impacts on crops are particulate matter such as smoke and dust, sulfur dioxide, nitrogen oxides, fluoride, ethylene, chlorine and other atmospheric pollutants.
