Microplastic pollution research has suffered from inadequate data and tools for spectral (Raman infrared) classification. Spectral matching often are not accurate microplastics identification cost-prohibitive. Lack of accuracy stems the diversity microplastic pollutants, which represented in libraries. Here, we propose a viable software solution: Open Specy. Specy is on web (www.openspecy.org) an R package. free allows users to view, process, identify, share their spectra community library....
There has been a rapid increase in the number of studies on both trash and microplastics recent years, with little data standardization. However, as is being produced by wide range practitioners differing study goals, researchers adhering to single standard may not be realistic. Post-hoc harmonization pathway that transforms non-standardized from prior into harmonized, comparable databases. Harmonization, however, hindered vast categorical descriptors used describe (thousands or more),...
Globally, rivers have been found to contain high concentrations of microplastics and are also the major conveyors microplastic pollution ocean. This has engendered an increased focus on sources, transport, fate in riverine systems. But how should we design monitoring plans for if our goal is quantify concentration, character, flux? Here present results campaigns conducted several systems draining coastal watersheds Southern California discuss lessons learned as well future directions support...
Abstract Urban areas are the primary source of human-made litter globally, and roadsides a accumulation location. This study aimed to investigate how arrives at determine rate composition roadside litter. We monitored select in Inland Empire, California, for abundance (count) (material, item, brand type). Receipt with sale time location information was used whether wind, runoff, or human travel were dominant transport agents. Only 9% receipts could have experienced wind direction not...
Abstract Despite global efforts to monitor, mitigate against, and prevent trash (mismanaged solid waste) pollution, no harmonized typology system has been widely adopted worldwide. This impedes the merging of datasets comparative analyses. We addressed this problem by 1) assessing state comparability, 2) developing a standardized framework relational tables tools, 3) informing practitioners about challenges potential solutions. analyzed 68 survey lists assess similarities differences in...
The Santa Ana River middle reach, a small coastal urban catchment in Southern California, USA experiences Mediterranean climate and lowflows dominated by wastewater effluent. macroplastic flux can inform watershed management of plastic pollution. However, continuous monitoring is not possible, so concentrations must be predicted during unobserved periods. We monitored concentration aimed to improve estimation using strategies commonly employed estimating mineral sediment flux. Floating size...
With the rapid expansion of microplastic research and reliance on semantic descriptors, there is an increasing need for plastic pollution data harmonization. Data standards have been developed but are seldom implemented across sectors, geographic regions, environmental media, or size classes pollution. Harmonization existing currently hindered by increasingly large datasets using thousands different categorical variable as well various metrics used to describe particle abundance differing...
Microplastics are a diverse suite of contaminants (Rochman et al., 2019) requiring variety data types to capture particle characteristics and study methodologies (Division Drinking Water, State Water Resources Control Board, California
