Konvensi ini memang tidak langsung memberikan efek yang signifikan namun dengan meratifikasi konvensi ini akan memberikan pengaruh terhadap kelangsungan ekspor bahan mentah terlebih sumber daya alam seperti bahan obat-obatan, bahan pangan dan bahan lainnya yang terkontaminasi oleh bahan kimia dan pestisida berbahaya. Ratifikasi konvensi ini akan mempersempit kemungkinan menurunnya kualitas keanekaragaman hayati yang sering dimanfaatkan untuk kebutuhan hidup. Selain itu adanya konvensi ini akan mencegah munculnya masalah terhadap lapangan pekerjaan bagi pihak-pihak yang terkontaminasi limbah maupun bahan kimia dan pestisida yang berbahaya seperti para petani, nelayan dan masyarakat pada umumnya. Jika ditelaah secara mendalam jumlah ekpor pada sektor pertanian setiap tahun terus mengalami penurunan, hal ini disebabkan oleh menurunya kualitas ekosistem persawahan akibat pemakaian pestisida yang berlebihan. Kata kunci : Konvensi Rotterdam, ratifikasi, hukum lingkungan.

This article complicates romances of infrastructural improvisation by describing infrastructural failures that expose researchers to hazardous chemicals in a Ugandan molecular biology lab. To meet project deadlines, to make careers and to participate in transnational collaborative projects, Ugandan biologists have to stand in for decaying or absent infrastructures with their bodies. Ugandan biologists hide such sacrifices from their international scientific partners and direct the blame elsewhere. An unclear culpability results precisely from the ways in which power works and is distributed across transnational scientific infrastructures.

The Impact

This study assessed the impact of increasing seawater surface temperature (SST) and toxic algal abundance (TAA) on the accumulation, tissue distribution and elimination dynamics of paralytic shellfish toxins (PSTs) in mussels. Mytilus coruscus were fed with the PSTs-producing dinoflagellate A. catenella under four simulated environment conditions. The maximum PSTs concentration was determined to be 3548 µg STX eq.kg−1, which was four times higher than the EU regulatory limit. The increasing SST caused a significant decline in PSTs levels in mussels with rapid elimination rates, whereas high TAA increased the PSTs concentration. As a result, the PSTs toxicity levels decreased under the combined condition. Additionally, toxin burdens were assessed within shellfish tissues, with the highest levels quantified in the hepatopancreas. It is noteworthy that the toxin burden shifted towards the mantle from gill, muscle and gonad at the 17th day. Moreover, variability of PSTs was measured, and was associated with changes in each environmental factor. Hence, this study primarily illustrates the combined effects of SST and TAA on PSTs toxicity, showing that increasing environmental temperature is of benefit to lower PSTs toxicity with rapid elimination rates.

The Rose

Rapid on-site evaluation (ROSE) is one of cytopathology’s “unique selling propositions.” The quality, speed, and ease of handling of the staining used is a critical factor for the efficacy of the ROSE procedure. Here, we describe a modification of rapid toluidine blue staining that can be performed within 25 s, provides excellent nuclear morphology, and is compatible with subsequent Papanicolaou staining of the slides. Furthermore, exposure to hazardous chemicals is minimized, as no organic solvents other than the alcohol-based fixative and glycerin for temporary mounting and coverslipping are required. We have used this protocol successfully in our ROSE practice and have not observed any discrepancies between toluidine blue- and permanent Papanicolaou-stained slides.
