Techniques for environment testing
Water Quality Testing
Spectrophotometer: Measures the concentration of specific compounds in water by analyzing the absorption of light at specific wavelengths.
Ion Chromatograph (IC): Separates and quantifies ionic species in water samples, such as anions (e.g., nitrate, phosphate) and cations (e.g., sodium, calcium).
Inductively Coupled Plasma Mass Spectrometry (ICP-MS): Highly sensitive technique for detecting and quantifying trace elements and heavy metals in water.
Total Organic Carbon (TOC) Analyzer: Measures the total organic carbon content in water, an important indicator of water quality.
Dissolved Oxygen (DO) Meter: Measures the amount of dissolved oxygen in water, which is crucial for aquatic life.
Soil Testing
X-Ray Fluorescence (XRF) Spectrometer: Determines the elemental composition of soil samples, including heavy metals and other contaminants.
Atomic Absorption Spectroscopy (AAS): Measures the concentration of specific elements in soil extracts, such as heavy metals and nutrients.
Gas Chromatography-Mass Spectrometry (GC-MS): Identifies and quantifies organic compounds in soil, including pesticides, herbicides, and other contaminants.
Fourier Transform Infrared (FTIR) Spectroscopy: Provides information about the functional groups and molecular structure of organic compounds in soil.
pH Meter: Measures the acidity or alkalinity of soil, which is essential for understanding nutrient availability and plant growth.
Soil Moisture Sensor: Measures the water content in soil, which is important for irrigation management and plant health.
Air Quality Testing and Monitoring
Gas Chromatograph-Mass Spectrometer (GC-MS): Identifies and quantifies a wide range of volatile organic compounds (VOCs) in air samples.
Fourier Transform Infrared (FTIR) Spectrometer: Measures the concentration of various gases in air, including carbon monoxide, carbon dioxide, and methane.
Particulate Matter (PM) Monitor: Measures the concentration of particulate matter (PM) in the air, such as PM2.5 and PM10.
Ozone (O3) Analyzer: Measures the concentration of ozone, a key component of smog and a secondary air pollutant.
Nitrogen Oxides (NOx) Analyzer: Measures the concentration of nitrogen oxides (NO and NO2), which are primary air pollutants.
Inductively Coupled Plasma Mass Spectrometry (ICP-MS): Detects and quantifies trace metals and heavy metals in air samples, such as lead, cadmium, and mercury.

Detection Techniques for Thallium in the Environment
Huangfu, Xiaoliu, et al. Chemosphere (2024): 142201.
Thallium (Tl) is a potentially toxic element with significant ecological and environmental risks. Recently, large amounts of Tl have been released into the environment through natural and human activities, raising increasing concerns. It is essential to accurately measure the levels of this hazardous and trace element in order to effectively manage and prevent its pollution.
The detection techniques for Tl in environmental samples include atomic absorption spectroscopy (AAS), voltammetry, inductively coupled plasma (ICP) methods, spectrophotometry, and X-ray techniques.
Analytical Techniques for the Determination of PFAS in Environmental Sample
Rehman, Abd Ur, Michelle Crimi, and Silvana Andreescu. Trends in Environmental Analytical Chemistry 37 (2023): e00198.
Per- and polyfluoroalkyl substances (PFAS) are a large class of synthetic chemicals used in many commercial products and applications, such as polymers, firefighting foams, cookware, and food packaging. PFAS pose a significant threat to the environment and human health due to their high stability, potential toxicity, and persistence in the environment.
The currently available methods for the detection of PFAS include gas chromatography or liquid chromatography (GC or LC) coupled with tandem mass spectrometry (MS/MS).
Determination of Antibiotics in Wastewater, Receiving Freshwater, and Marine Environments
Serra-Compte, Albert, et al. Environmental Pollution 271 (2021): 116313.
The presence of antibiotics in the water environment is an increasingly concerning issue. The highest concentrations are typically detected in wastewater, reaching several μg/L, while much lower concentrations, below 0.001 μg/L, are usually measured in surface and groundwater.
Two different approaches are combined to assess the potential environmental risks posed by antibiotics: i) an effect-based method based on microbial growth inhibition, and ii) an analytical method based on liquid chromatography-mass spectrometry (LC-MS). The first method, after adjustment and validation, can be used to screen four antibiotic families, particularly macrolides/β-lactams, quinolones, sulfonamides, and tetracyclines. The LC-MS method is used for the identification and quantification of target antibiotics. The results are then combined with ecotoxicological data from the literature to determine the environmental risk.
