Environmental Monitoring & Analysis

Over the past few decades, industrialized societies have been developing new chemicals and producing large quantities of existing chemicals every year. These chemicals have contributed greatly to improving human health and lifestyle, but they are released into the environment during production, transport, utilization or disposal, and once in the environment they can have harmful side effects, especially on human health and ecosystems, through the persistence of large residues in the environment or through bioaccumulation in the food chain. In order to be able to control and manage the environmental risks posed by chemicals, it becomes essential to identify and quantitatively assess environmental risks. Therefore, environmental analytical chemistry has evolved from traditional analytical chemistry to a mature discipline, and monitoring of the environment is a very challenging and dynamic field because it involves the most uncertain and error-prone phases, requiring scientists to obtain representative samples from complex matrices, expensive instrument identification and quantification of contaminants at the parts-per-million level to cope with the changing regulatory requirements in monitoring drinking water, wastewater, ambient/emitting air, and solid/hazardous waste. Wet chemistry techniques offer a variety of methods for environmental sample preparation, including different digestion procedures for metals and inorganic metals, and a variety of extraction and separation methods for volatile and semi-volatile compounds. As wet chemistry testing is increasingly becoming automated, BOC Sciences has been equipped with the latest instruments to provide reliable and efficient analysis of substances for your environmental monitoring & analysis.

Environmental Aggregate Organic Constituents Analysis

The presence of tens of thousands of toxic organic compounds in soil, water, and waste makes the analysis of organic compounds more challenging than a limited number of inorganic analytes. Organic constituents in the environment are often present as complex mixtures in contaminated samples, and environmental chemists often rely on wet chemistry techniques to identify and quantify groundwater, aqueous and soil samples. Combined with advanced instrumentation and standardized analytical processes, our chemists can identify and quantify target organic constituents by using a variety of organic reagents to break down environmental samples and dissolve the organics in appropriate solvents. Our organic labs can safely handle samples from virtually any matrix - drinking water, wastewater, groundwater, soil, petroleum, sludge, etc.

Environmental Inorganic Nonmetallic Constituents Analysis

There are many anthropogenic contaminants of inorganic metal compounds in surface and groundwater, such as chlorides, fluorides, sulfates, phosphates, and nitrate-nitrogen. Nutrients containing nitrogen, phosphorus and potassium have been identified as one of the major causes of serious environmental pollution. In addition, dissolved oxygen, free chlorine, total chlorine and total sulfide in water need to be strictly monitored to ensure the safety of fish and other aquatic organisms and the health of the ecosystem. At BOC Sciences, our classic wet chemistry analysis of inorganic nonmetallic constituents includes nutrients (ammonia, nitrite, nitrate and phosphate), minerals (calcium and magnesium hardness, chlorine, fluoride and sulfate), cyanide, and phenol. In combination with our professional colorimetric, titrimetric and potentiometric methods, our experts are able to determine and quantify the chemical composition and properties of non-metallic inorganic substances in the environment, ensuring that the chemical composition of water and soil in the environment meets regulatory requirements and guidelines.

Environmental Physical & Aggregate Properties Analysis

Many types of floating, coarse-grained and particulate matter are present in soils and wastewater. This type of contamination is the result of its deposition, clogging, anaerobic degradation, and its potential adsorption to metals or organic compounds or microorganisms. Aggregates in the environment include soluble fractions, suspended solids and microorganisms in sewage, waste and soil. We are equipped with a comprehensive analytical laboratory that provides complete wet chemistry testing and is capable of qualitative or quantitative analysis of inorganic materials, metals, and microorganisms in the environment. In addition, we are able to test most aggregate properties and conventional wet chemical physical parameters in the environment including acidity, alkalinity, pH, viscosity, hardness, conductivity, salinity, turbidity, temperature, color, melting range, refractive index, ratio, and optical rotation. BOC Sciences is committed to offering a wide range of supporting analyses for customers in different industries to meet different applications.
