“…Due to the complex nature of the samples that are commonly encountered during environmental investigations (Cattle et al 2004 ; Kaljurand 2014 ; Spikmans 2015 ), methods that are developed for in-field application should not only be capable of detecting common target compounds in a range of matrices but should also be capable of screening and identifying non-target compounds using library searches (Galuszka et al 2015 ; Lam et al 2019a ). This would provide for a generic approach and would generate sufficient information to guide the on-site investigation until confirmatory results are provided by the reach-back laboratory (Lam et al 2019b ; Valcárcel and Cárdenas 2005 ).…”

Environmental pollution incidents generate an emergency response from regulatory agencies to ensure that the impact on the environment is minimised. Knowing what pollutants are present provides important intelligence to assist in determining how to respond to the incident. However, responders are limited in their in-field capabilities to identify the pollutants present. This research has developed an in-field, qualitative analytical approach to detect and identify organic pollutants that are commonly detected by regulatory environmental laboratories. A rapid, in-field extraction method was used for water and soil matrices. A coiled microextraction (CME) device was utilised for the introduction of the extracted samples into a portable gas chromatography–mass spectrometry (GC–MS) for analysis. The total combined extraction and analysis time was approximately 6.5 min per sample. Results demonstrated that the in-field extraction and analysis methods can screen for fifty-nine target organic contaminants, including polyaromatic hydrocarbons, monoaromatic hydrocarbons, phenols, phthalates, organophosphorus pesticides, and organochlorine pesticides. The method was also capable of tentatively identifying unknown compounds using library searches, significantly expanding the scope of the methods for the provision of intelligence at pollution incidents of an unknown nature, although a laboratory-based method was able to provide more information due to the higher sensitivity achievable. The methods were evaluated using authentic casework samples and were found to be fit-for-purpose for providing rapid in-field intelligence at pollution incidents. The fact that the in-field methods target the same compounds as the laboratory-based methods provides the added benefit that the in-field results can assist in sample triaging upon submission to the laboratory for quantitation and confirmatory analysis.

The Mediterranean Sea has recently been described as one of the most affected marine environments with regards to microplastics. Existing data relating to microplastics on Mediterranean surface waters have shown not only an evident heterogeneous distribution, but also marked geographical differences between the Mediterranean subregions. To date, standardized methodologies for the sampling and analysis of microplastics are still lacking, which therefore hinders the comparison of the reported data. This review summarizes the currently used methodologies for sampling and identifying microplastics in surface water, with the intention of contributing to establishing standardized methodologies. In addition, the importance of a forensic approach for the development of more complete and robust strategies and protocols to assess the extent of the phenomenon of microplastics is highlighted.
