Lowering the water‐soluble chromium content of cement to < 2 ppm has been suggested to diminish tile risk of allergic hand dermatitis caused by chromium among construction workers. The prevalence of chromium dermatitis was determined for a representative sample of 913 house construction workers and 707 concrete element prefabrications workers, with a questionnaire and clinical examination, before the use of cement with such H low content of water‐soluble chromium was Lined on Finnish… 
The dermal toxicity of cement
It is indicated that cement and concrete should be treated as hazardous materials, and that workers handling such products should reduce exposure wherever possible.
Dermatoses in cement workers in southern Taiwan
It is concluded that cement workers in southern Taiwan had a high prevalence of skin problems related to cement use, and Protective measures, work practice, and physician education should be improved to prevent or manage such problems.
Contact with wet cement: report of a case
A case presented to the ED with acute ulcerative dermatitis related to working with wet cement without protection is reported and the potential hazards as a result of working with cement are illustrated.
Cement-Induced Chromate Occupational Allergic Contact Dermatitis
Prolonged exposure to cement before development of symptoms was associated with chronicity, and the adoption of the European legislation in Israel is recommended, to reduce the prevalence of chromate OACD from cement.
Effectiveness of the European chromium(vi) directive for cement implementation on occupational allergic contact dermatitis occurrence: assessment in France and the U.K.
This work has shown that through the addition of ferrous sulphate to the dry product, allowing to reduce chromium VI to chromium III which is less sensitizing, the price of hydrated cement can be reduced.
Contact Dermatitis in Construction Workers in Northeastern Italian Patch Test Database Between 1996 and 2016
The effectiveness of EU regulations in reducing chromate sensitization in CWs and the overall incidence of occupational contact dermatitis decreased significantly, however, sensitization to other haptens is increasing, though improvement of protective measures is compulsory.
Occupational contact allergy in bricklayers, tile setters etc. - Current spectrum of sensitization and recent time trends
Thanks to the usage of chromate-reduced cement, chromate sensitization continues to decline in the building trade, and the increase of epoxy resin sensitization must prompt intensified prevention efforts.
Occupational contact allergy in the building trade in Germany: influence of preventive measures and changing exposure
Reducing Cr VI content of cement is useful in preventing allergic cement eczema, as previously found in Scandinavia, and the increasing prevalence of contact sensitization to epoxy resin components in the building trade is alarming.
Effect of hand dermatitis on the total body burden of chromium after ferrous sulfate application in cement among cement workers
The effect of dermatitis on the total uptake of chromium in cement with or without FeSO4 has not been previously explored, andFerrous sulfate added to cement has been used to reduce the prevalence of dermatritis in workers.
Contact allergy in construction workers: results of a multifactorial analysis.
Dichromate is still an prominent allergen in construction workers; as yet, there is only weak evidence of a decrease in Germany, and the addition of ferrous sulphate to cement should be promoted further.


Follow‐up of workers from the prefabricated concrete industry after the addition of ferrous sulphate to Danish cement
A larger number of chromate‐sensitized workers required medical services and topical steroid treatment than did those who were not sensitized to chromate, and the worse medical prognosis could in part be due to the fact that some of these had secondary contact sensitivity to cobalt and rubber chemicals.
Prevalence of cement eczema in Denmark before and since addition of ferrous sulfate to Danish cement.

There was a statistically significant decrease in the prevalence of chromate allergy and hand eczema following the addition of ferrous sulfate, but there was no change in the frequency of skin irritation.
Cement dermatitis in underground workers during construction of the Channel Tunnel.
A surveillance programme aiming to monitor and investigate the men working closely with cement as well as other groups of workers with skin problems, found that many gave a history of a single episode of dermatitis during a particularly hot and wet phase of tunnelling.
Chromate sensitization and elicitation from cement with iron sulfate.
Although iron sulfate had been added to the cement, high chromate concentrations were found in many samples of cement to which these workers were exposed, and allergic contact dermatitis from chromate is reported here in 3 workers with hand dermatitis and exposure to cement containing Iron sulfate.
Occupational hand eczema in an industrial city
The type of hand eczema that is mostly dependent on occupation is irritant contact dermatitis, which is more common among people reporting some kind of occupational exposure.
Reduction of chromate in cement by iron sulfate
Cement dermatitis is connected with chromate sensitivity. It can therefore be expected that “elimination” of chromate in cement would decrease the number of cases of cement dermatitis.
Changing patterns in chromate allergy
To investigate whether the incidence and pattern of contact sensitivity lo chromate have changed in recent years, after a voluntary addition of iron sulphate to Swedish cement (11. the test results
Antiallergic drugs and the immune response
Results show cromolyn to have an enhancing effect, theophylline and ketotifen a suppressing effect, whereas the remainder show no effect on the immune response.
