Copper Sulphate, CuSO
4
, is an inorganic compound, a potent
oxidant, with a long history of use especially as a fungicide,
bactericide and also a killer for smaller animals like snails for
agriculture. The heavy metal, Copper (Cu) is an essental mineral
although in excess is very harmful [1,2]. Copper sulphate can be
available as powder, crystals or liquids and can be exposed by
skin contact, inhalaton or by ingeston in the way of self harm
or by accident. Copper causes damage to the cell membranes
of the tssue cells making them swollen and causes cell death
[2]. Red blood cells (causing haemolysis), myocytes (causing
rhabdomyolysis) and hepatocytes (causing acute hepatts) are
the commonest tssues afected [3]. Once absorbed copper occur
in plasma as ceruloplasmin (Cp) bound to protein and excreted
largely in faeces. It has a biological half-life (BH) of 13-33 days.
When in excess it may get deposited mainly in the liver [4].
Plasma level of copper and other reference ranges related to
copper metabolism in human is as follows; this data is adapted
from Medscape artcle on Copper by Joshua Sloan- htps://
emedicine.medscape.com/artcle/2087780-overview
Free serum copper: 1.6-2.4 μmol/L or 10-15 μg/dL
Total copper: 10-22 μmol/L or 63.7-140.12 μg/dL
Serum ceruloplasmin: 2.83-5.50 μmol/L or 18-35 μg/dL
24-hour urine copper 0.3-0.8 μmol or 20-50 μg
Liver copper 0.3-0.8 μmol/g of tssue or 20-50 μg/g of tssue
Copper Sulphate Poisoning (CSP) is rare, but a signifcant entty
due to its higher risk of mortality even with smaller doses of
ingeston. Features of toxicity can manifest even with a dosage of
1 g and dose of 10-20 g could even be lethal [5]. However clinical
manifestatons and complicatons likely depend on other factors
like, tme taken to seek medical atenton, quality of medical care
one would receive, especially at emergency care and patent’s
medical background. This artcle partcularly concentrates
on clinical manifestatons and management of CSP in a more
illustrated manner, to provide a guideline to the clinician.
Signs and Symptoms
There is mult-organ involvement with wide range of severity
of each organ involved. Therefore clinical syndrome one would
present will fall in to a large spectrum of possibilites.
1. Exposure related signs and symptoms
Skin contact – irritaton, allergy if the person is allergic to
compound.
Eye – irritaton
Inhalaton – breathing difculty
Ingeston – nausea, vomitng and diarrhoea. Vomitus and
diarrhoea can be greenish or bluish in colour [1].
2. Symptoms due to erosive gastropathy
Corrosive injury to gastric mucosa – epigastric pain and
tenderness, nausea, vomitng
Mucosal erosions or ulcers causing upper gastro-intestnal
bleeding – haematemesis and malaena
3. Intravascular haemolysis
Oxidatve damage to red cell membrane causes acute
haemolysis – icterus, dark urine (Haemoglobinuria) and
pallor.
4. Methaemoglobinaemia – cyanosis
Absorbed Cu

ions oxidises Fe

ions in Hb
generatng Methaemoglobin. These carry less Oxygen
than normal Hb. Further, the hybrid Hb (ferri-ferro Hb)
