Environmental health risk assessment has a long history in both the United States and Russia. Risk assessment methods have arisen and developed to protect against the dangers of the forced use of tens of thousands of chemicals in the modern world. Because chemicals play such an important role, it is impossible to ban their use altogether, and the task of their safe use becomes more and more critical. With the solution of this problem, the creation of modern environmental legislation began, based on an assessment of the hazard or potential hazard associated with the impact of these substances on humans. Risk assessment has become the scientific basis for calculating exposure limits for many chemicals that pollute the environment. Since compliance with environmental legislation is costly to industry, methods have been developed. They are being improved on to quantify the burden of proof and the appropriateness of environmental quality regulation. Environmental Health Risk Assessment was first developed by the United States Environmental Protection Agency (US EPA). Russia has accumulated a great deal of practical experience in assessing environmental risks and developing appropriate methodological recommendations. Thus, the basis was created for long-term cooperation between the two countries. This article summarizes the history of such collaboration, including a joint project to disseminate practical risk assessment in Ukraine.

In the 1990s several biocontrol agents on that containedBurkholderiastrains were registered by the United States Environmental Protection Agency (EPA). After risk assessment these products were withdrawn from the market and a moratorium was placed on the registration ofBurkholderia-containing products, as these strains may pose a risk to human health. However, over the past few years the number of novelBurkholderiaspecies that exhibit plant-beneficial properties and are normally not isolated from infected patients has increased tremendously. In this commentary we wish to summarize recent efforts that aim at discerning pathogenic from beneficialBurkholderiastrains.

High Volume Air Sampler (HVAS) adalah alat pengambil sampel partikulat di udara ambien yang memiliki prinsip kerja dengan sistem vakum dengan menarik udara lingkungan sekitar melalui inlet dengan ukuran-selektif dan melalui filter berukuran 20,3 x 25,4 cm (8” x 10”) pada laju alir 1.132 liter/menit. Pada standard US-EPA (United States Environmental Protection Agency) sering menemui alat sampling yang digunakan memiliki bentuk yang besar (45,5” x 22,5” x 20”) dan berat sekitar 15-20 kg, sehingga timbul ide penelitian untuk membuat desain modifikasi alat pengambil sampel partikulat ambien dengan bentuk yang lebih fleksibel, ringan dan ringkas dengan menggunakan metode uji Gravimetri. Tahap awal penelitian ini adalah melakukan identifikasi peralatan HVAS standard dan peraturan yang mengatur tentang pengujian partikulat. Kemudian merubah bentuk fisik luarnya (memperkecil) tanpa merubah fungsi yang ada didalamnya dan diuji coba bersamaan kinerjanya. Hasil uji coba diolah menggunakan statistik. Dengan menggunakan hasil identifikasi HVAS standard EPA, maka didapat desain modifikasi HVAS dengan dimensi unit utama 15,35” x 15,35” x 10” (PxLxT), kaki knockdown sepanjang 4,5” dari hollow 4x4cm sebanyak 12 buah, dan memiliki berat total sekitar 23 lbs / 10,58 kg.Keseluruhan proses pembuatan alat ini hanya memerlukan biaya sebesar Rp.11.350.000,-. HVAS modifikasi memiliki kemampuan yang tidak beda nyata dengan HVAS existing berdasarkan nilai Anova, dimana nilai P =0,985. HVAS modifikasi yang didesain telah memenuhi standard dengan bentuk lebih kecil dan lebih ringan, sehingga bisa memudahkan dalam penyimpanan dan mobilisasi pengujian sampel partikulat ambien. Berdasarkan penggunaan material untuk pembuatan HVAS modifikasi didapatkan angka yang lebih murah karena reduksi material pembentuk rangka HVAS. HVAS modifikasi dapat dipergunakan sebagai alat sampling untuk pengujian sampel partikulat di udara ambien.
