ADVERSE EFFECT ON PRODUCTION OF CONSTRUCTION MATERIAL

In construction there are many type of construction material used in order to complete the project.
There are:

  • cement                               aggrigate                                        
  • sand                                   clay
  • asbestos                             lime
  • steel                                   bituminous
  • aluminium                         glass/silica
  • pvc                                    water proofing material
  • paint                                 zinc
  • timber                              
All of the material above will be pollute  in :
  • air pollution
    • gas emission
    • chemical substance to the air
  • water pollution
    • chemical discharge to river
    • wastage discharge to landfill
Cemenr Production
  • water pollution minimise
  • noise pollution 
  • air pollution-dust.NO x,SO x,CO,CO2,TOC,HF,HCF and NH3
Quarry Production
  • disturbance of land and vegetation
  • disturbance of river beds and costal marine
  • dust
  • noise
  • vibration
  • traffic
  • visual aspect
  • the discharge of contaminations into air,water,land and costal area
Sand Extraction
  • Biodiversify-Impacts on related ecosystem (fisheries)
  • Land loses-Inland and coastal through erosion
  • Hydrological -Change in water flow,flow regulation and marine current
  • Water supply-Lowering of water table and pollution
  • Infrastructure-Damage to bridge,river embankments and coastal infrastructure
  • Landscape-Coastal erosion ,changed in deeltaic structure,quarries and pollution of river
Asbestos Production
  • crysotile asbestos/white asbestos
  • benign condition of pleura
  • Lung cancer
  • Asbestosis
  • Mesothelioma
  • gastro-intestinal cancer
  • laryngeal cancer
  • autoimmunity
  • genotoxis
  • irrative
Steel Production
  • gases emission-CO2,NOx,SOx,
  • fumes-iron oxide,cadmium,lead,chromium,nickel,zinc,copper and hydrocarbon
  • cancer and respiratory problem
Aluminium Production
  • bauxite-source of aluminium
  • exploration of bauxite pollute water supply,soil erosion,flooding and etc
  • production emission-flouride,PFC,PAH,SO x,Dust,Metal,NOx,CO,COS,CO2 and others
  • coz Alzheimer and cancer
PVC Production

Paint Production

  • VOC compound such as glycols,toulene,hydrocarbon,xyele,ammonia,carcinogen and mutagen
  • pigment such as cadmium and titanium oxide
  • Formaldelayde
  • Acetaldelayde
  • Mercury
  • PGE
Timber Logging

  • forest degradation
  • animal richness decline
  • habitat loss
  • increase waterruoff,erosion and flood
  • reduce carbon by 15%
  • increase sendiment and turbidity
  • lowering water quality
Claybrick Production
  • air/water pollution
  • SOx
  • NOX
  • CO
  • CO 2
  • lead
  • dust
  • hydocarbon
  • SS
  • Ash
Limestone powder

  • calcium phosphide dangerous to aquatic used
Bituminous Production and Water proofing
  • respiratory
  • cutaneous
  • ingestion
  • carcinogenic(probably)
Glass/Silica Production
  • production-emission Sox,NOx,Sand and Mineral wastage,VOC
Zincalume Production
  • prodution-emission of SOx,NOx,CO 2
From the above information,the pollution happened in three stage:

  • mining
  • production
  • wastage
TO CONTROL
  • set a policies and guideline
  • to strengthen the enforcement
  • to give information regarding green house emission,ozone layer and so on
