What is electronic waste?
From this
To this
Risks Health Environment Financial loss
Health Risks Lead PVC Brominated Fire retardants Barium Chromium Mercury Beryllium Cadmium
Metal casing plastics Cables and wires Chip resistors, detectors and conductors Circuit boards Switches and relays
CRT yokeCircuit boards Connectors and chips Cables and wires Metal band and frit Panel glass Funnel glass
Lead CRT – funnel, panel (old) and frit Circuit boards
Lead damage to the nervous systems, blood system and kidneys
Children suffer developmental effects and loss of mental ability, even at low levels of exposure. Brain or nerve damage Digestive issues Hearing problems Stunted growth Lead
Use PPE Don’t burn Don’t dismantle for parts Environmental hazard Toxic Source: Solder, batteries
Plastics Cables - PVC Computer and monitor cases – mainly ABS
PVC Cancer Disruption of the endocrine system Reproductive impairment Impaired child development and birth defects Neurotoxicity (damage to the brain or its function), and Immune system suppression
Dioxin
Brominated Fire Retardants Monitor cases Cables Computer cases Circuit boards Connectors
neurotoxic effects Brominated Fire Retardants endocrine disrupters linked to thyroid and liver damage cancer of the digestive and lymph system
Flame retardant: Polychlorinated Biphenyls (PCB’s) and Polychlorinated Diphenyl-Ether Use PPE Don’t burn Environmental hazard Toxic Source: Plastic casing, plastic wiring casing
Barium Old CRTs
Barium Gastrointestinal disturbance Changes in blood pressure Muscle weakness Breathing difficulty
Chromium Metal hardening and corrosion protection in metal housing and plates
Chromium Skin reactions Bronchitis Nerve damage DNA damage, hereditary effects
Hexavalent Chromium Use PPE Don’t dismantle for parts Don’t burn Toxic Source: Plating, anti- corrosion applications, plastic pigments
Beryllium Motherboards Connectors
Beryllium berylliosis Lung cancer
Mercury Circuit boards Mercury switches and fluorescent tubes Batteries
Mercury gastrointestinal problems Skin rashes Nerve damage kidney damage
Mercury Use PPE Use a spill kit Don’t burn Don’t dismantle for parts Environmental hazard Toxic Source: Switches, sensors, contacts, lamps
Cadmium Chip resistors Phosphorescent coatings Batteries Cables and wires Semi conductors
Cadmium Lung damage Grey babies Weak bones Kidney damage
Cadmium Use PPE Don’t burn Environmental hazard Don’t dismantle for parts Toxic Source: Solder, plastic casing, coatings
Toxic components in ewaste include: Gases from fridges, AC and cooling equipment Circuit boards containing heavy metals such as lead & cadmium Batteries Cathode ray tubes Brominated flame-retardants used in printed circuit boards, cables and plastic casing.
Toxic components in ewaste include: Poly Vinyl Chloride (PVC) coated copper cables and plastic casings that release highly toxic dioxins & furans when burned Mercury in flat panel screens Mercury in fluorescent tubes Poly Chlorinated Biphenyls (PCBs) present in older capacitors & transformers
Ewaste that needs special care Fridges – Oils – Foams – Gases Televisions and monitors – CRTs – LCD Bulbs and lamps Batteries
