By Dipo Olowookere\r\nA new study co-designed by Kim, Seung-Kyu, Professor at Incheon National University and Greenpeace East Asia has showed that over 90 percent of sampled salt brands globally were found to contain microplastics.\r\nIt was gathered from the study, which was obtained by Business Post that the highest number of the sampled salt brands containing these microplastics came from salt sourced in Asia.\r\nThe study, which has been published in Environmental Science & Technology, a peer-reviewed scientific journal, analysed 39 various salt brands globally, showing that plastic contamination in sea salt was highest, followed by lake salt, then rock salt - an indicator of the levels of plastic pollution in the areas where the salt was sourced.\r\nHowever, only three of the salt brands studied did not contain any microplastic particles in the replicated samples.\r\n\u201cRecent studies have found plastics in seafood, wildlife, tap water, and now in salt. It\u2019s clear that there is no escape from this plastic crisis, especially as it continues to leak into our waterways and oceans.\r\n\u201cWe need to stop plastic pollution at its source and therefore call upon the accountability of big corporates in this crisis. They need to reduce their plastic footprint and take on the problem they have created,\u201d said Awa Traor\u00e9, West Africa Oceans Campaigner at Greenpeace Africa.\r\n\u201cWe also need to see the effective implementation of single use plastics ban laws in African countries and not only strong commitments from governments. For the health of people and our environment, it\u2019s incredibly important that these big corporates be pushed to go beyond recycling, start taking responsibility for their contribution to plastic pollution and begin reducing single-use plastic production,\u201d continued Awa Traor\u00e9.\r\nBuilding on previous studies of microplastic pollution in salt, this research is the first of its scale to look at contaminant levels of the geographical spread of sea salt, and its correlation with environmental discharge and pollution levels of plastics.\r\nThis new research findings of plastics in salt with the two sample results for Senegal showing the types of salt, the level of a yearly one ton 49 riverine plastic emission, and the presence of Microplastics in sea salt, are good indicators of the correlation between abundance micro plastics in sea salts, riverine plastic emissions, and micro plastic level in seawater. It\u2019s another big critical highlight that plastic pollution is a global crisis, and Africa, in particular, must take this issue seriously, as the ecosystem and human health in African seas could potentially be at greater risk because of severe maritime microplastics pollution.\r\nAssuming intake of 10 grams per day of salt, the average adult consumer could ingest approximately 2,000 microplastics each year through salt alone, as the study suggests. Even after discounting the highly contaminated Indonesian salt sample from this study, the average adult could still be consuming many hundreds of microplastics each year.\r\n\u201cThe findings suggest that human ingestion of microplastics via marine products is strongly related to plastic emissions in a given region,\u201d said Professor Kim, Seung-Kyu, corresponding author of the study. \u201cIn order to limit our exposure to microplastics, preventative measures are required, such as controlling the environmental discharge of mismanaged plastics and more importantly, reducing plastic waste\u201d he added.\r\nEarlier this month, Greenpeace along with the Break Free From Plastic coalition released a report naming Coca-Cola, PepsiCo, and Nestl\u00e9 as among the most frequent companies whose packaging relies on the single-use plastics that pollute our oceans and waterways globally.
