There is growing concern that VOC emissions from materials used indoors in buildings should be monitored to ensure that building occupants are not exposed to potentially harmful chemicals. Monitoring can be absolute (determining, for example, emission rates in micrograms per square meter-hour),
The global golf ball market was estimated to be over one billion dollars in 2017. It is estimated that each year, over 300 million golf balls are lost in the United States, alone. Golf balls are not recyclable or biodegradable, so if not recovered, the balls are left in waterways and woodlands.

Plastics have become a major source of pollution due to their ubiquitous use in a wide array of products. Most plastics are not readily biodegradable and can wind up as litter or are simply disposed of in landfi lls. It is estimated that only 9% of the plastic in the US is recycled [1]. Plastics discarded into the environment can be ingested by animals, break down into smaller particles which can also be ingested, or leach other compounds into the environment which can potentially cause damage. Leachates can include plasticizers, fl ame retardants, blowing agents, UV stabilizers, dyes and a host of other compounds added to the polymers.

Liquid-liquid extractions have long been performed manually and are used to extract and concentrate analytes from aqueous matrices. Inclusion of liquid-liquid extraction in many official methods...
Bisphenol A (BPA) is a widely produced chemical used as a precursor in the formation of plastics (polycarbonate) and coatings for food and beverage containers

Micro- and nanoplastics pollution in oceans, lakes and other water sources is an on-going and well-documented issue. Sources and entry ways of these plastics include grey water, surface runoff, and litter. Grey water is defi ned as the relatively clean wastewater from sources such as baths, sinks, washing machines and dishwashers. The very small plastic particle size precludes effi cient removal during the wastewater treatment process. As a result, fi sh and other aquatic life ingest the plastics, which introduces them into the food chain and causes possible adverse effects.

Stir Bar Sorptive Extraction (SBSE) and Solvent Assisted Stir Bar Sorptive Extraction (SA-SBSE) are firmly established techniques for extraction of compounds from various matrices, with the latter technique offering significant increased capacity for concentration of hydrophilic/polar compounds. In this application note this difference is explored by applying both SBSE and SA-SBSE to a berry-flavored yogurt followed by GC-MS after liquid desorption of the stir bars.
Stir Bar Sorptive Extraction (SBSE) is an innovative and efficient method for the extraction of drugs and pharmaceuticals from blood-, urine- and tissue samples in a forensic ...
Synthetic cathinones (also known as Bath Salts) are a group of drug compounds designated as Novel Psychoactive Substances (NPS). They are unregulated, mind-altering substances with no actual approved medicinal use.
A procedure is presented for quantification of Ethyl Carbamate at low μg/L levels in distilled spirits. A 100 μL large volume injection was used followed by orthogonal 2-dimensional GC-MS with heartcutting. The direct large volume injection ensured sufficient availability of analyte without an initial sample preparation step,
