How Do Factories Cause Air Pollution? | SciencingFactories produce air pollution by burning fuels, carrying out chemical processes and releasing dust and other particulates. Air pollution can be controlled with filters and scrubbers, and by taking steps to minimize the generation of pollution at the source.

CIP 1 - Dusting Concrete Surfaces WHY Do Concrete Floors Dust A concrete floor dusts under traffic because the wear-ing surface is weak. This weakness can be caused by: a. Any finishing operation performed while bleed wa-ter is on the surface or before the concrete has fin-ished bleeding. Working this bleed water back into the top 1/
Dusts can also come from organic chemicals (e.g., dyes, pesticides). However, in this OSH Answers document, we are only considering dust particles that cause fibrosis or allergic reactions in the lungs. We are not including chemical dusts that cause other acute toxic effects, nor long term effects such as cancer for example.
The Dangers of Exposure to Construction Site Dust Construction dust can be a significant problem for many people. Airborne dust can cause a wide range of health and lung problems for construction workers, but it also creates a concern for people living near construction sites.
Exposure to airborne dust may cause immediate or delayed irritation or inflammation. Eye contact by larger amounts of dry powder or splashes of wet Portland cement products may cause effects ranging from moderate eye irritation to chemical burns and blindness, requiring immediate first aid (see Section 4) and medical attention.
Silica dust - Cancer Council AustraliaSilica dust is harmful when inhaled into your lungs. As it is 100 times smaller than a grain of sand, you can be breathing it in without knowing. Exposure to silica dust can lead to the development of lung cancer, silicosis (an irreversible scarring and stiffening of the lungs), kidney disease and chronic obstructive pulmonary disease.Cement Dust Exposure and Perturbations in Some .Background . Cement dust inhalation is associated with deleterious health effects. The impact of cement dust exposure on the peak expiratory flow rate (PEFR), liver function, and some serum elements in workers and residents near cement factory were assessed. Methods . Two hundred and ten subjects (50 workers, 60 residents, and 100 controls) aged 18–60 years were studied.
