Abstract

تم إجراء تحديد كمي ونوعي للملوثات المنبعثة في بيئة العمل، بما في ذلك الغبار ومكوناته من الكربون العضوي وغير العضوي في أحد مصانع إنتاج العوازل الكهربائية. استخدمت مرشحات قطرها 5 ميكرون لتجميع الغبار المنبعث وتحضيرها في محلل الكربون للمكونات العضوية وغير العضوية. نتائج التحليل أظهرت وجود نسبة عالية من انبعاث الغبار ومكوناته من انبعاثات الكربون العضوية وغير العضوية في وقت الذروة لجميع أماكن العمل في وحدات مختارة. حيث بلغت الإيداعات ( 244.0 مايكروغرام.م-3 ) وأقل قراءة ( 59.0 مايكروغرام.م-3. ). الإيداعات اليدوية سجلت تراكيز عالية من الكربون العضوي حيث بلغت ( 916.0 مايكروغرام.م-3 ) وأقل قيمة (4.0 مايكروغرام.م-3). كانت أعلى تراكيز للكاربون غير العضوي الكلي باستخدام الايداع اليدوي خلال يوم كامل للعمل /8 ساعات ( 440.0 ملي غرام.متر-1 .8 ساعة-1) وأقل تركيز (2.8 ملي غرام.متر-1 .8 ساعة-1 ) . وكان اعلى تركيز للكاربون العضوي (117.0 ملي غرام.متر-1 .8 ساعة-1 ) وأقل تركيز (2.0 ملي غرام.متر-1 .8 ساعة-1 ).خلال الإيداعات اليدوية والآلية. جميع تركيزات الغبار ومكوناته من الكربون العضوي وغير العضوي هي خارج حدود المعايير القياسية الدولية. التعرض لهذه الانبعاثات خلال وقت عمل فعلي قدره 8 ساعات في اليوم يتطلب التزامات بتدابير السلامة الفردية والجماعية للحفاظ على سلامة العاملين.

Highlights

  • For more than 200 years, chemists have divided carbon compounds into two groups. Those that were isolated from nature were called organic carbon compounds, while those extracted from a biotic and minerals were inorganics

  • The WHO includes the protection factor for sensitive plant and animal organisms as well as human health, so the small scale was based on two indicators, Particulate Matter 10 micron diameter (PM10), which is preferred according to the previous specifications is 50 μg.m-3 for a period of 24 hours in ambient air and 20 μg.m-3 annual mean

  • Results reviled the dust emissions concentrations of organic carbon in the mechanical lathing unit for cutting Phenolic Carbon Insulators (PCI) were (244.0 μg.m-3) and this result is higher than the International Standards Units (ISU) [9] and the lowest inorganic emissions (59.0 μg.m-3)

Summary

1- Introduction

For more than 200 years, chemists have divided carbon compounds into two groups Those that were isolated from nature (plants or animals) were called organic carbon compounds, while those extracted from a biotic and minerals were inorganics. Pollutants of major public health concern consist of particulate matter, carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2) and sulfur dioxide (SO2) [2] This indoor environment is often contaminated with differences air pollutants; the concentration of these pollutants may reach high peak levels due to the small spatial size. The WHO includes the protection factor for sensitive plant and animal organisms as well as human health, so the small scale was based on two indicators, Particulate Matter 10 micron diameter (PM10), which is preferred according to the previous specifications is 50 μg.m-3 for a period of 24 hours in ambient air and 20 μg.m-3 annual mean. The study aims at quantitative and qualitative determination of the components of dust particles emitted within the work environments due to mechanical activities such as lathing and pressing of organic carbon materials for the production of insulators through the collection and recovery of dust and the determination of its carbon components
