Acute lead intoxication in a female battery worker: Diagnosis and management
This article presents a case of acute lead intoxication in a 33 year female having worked three months as a cleaner in a battery manufacturing plant. She complained of malaise that had developed in the previous two weeks. Pallor of skin and conjunctiva was the only sign found in physical examination. The blood test on admission revealed normochromic anaemia. Endoscopic investigation of the gastrointestinal system was negative for bleeding. The bone marrow biopsy was unrevealing. At baseline, no attention had been paid to patient's occupational history. The patient's occupational history was later re-evaluated, and she was screened for lead intoxication. The increased levels of the lead related biomarkers of exposure and effect confirmed the diagnosis. The patient received an oral chelating agent, resulting in an improvement in clinical picture. No side effects and no rebound effect were observed. This case report emphasizes the importance of the occupational history in the context of the differential diagnosis. Moreover, this report indicates that lead remains a significant occupational hazard especially in the small scale battery industry.

Guidance for the identification and control of safety and health hazards in metal scrap recycling
In the recycled metals sector, the most common occupational diseases are those caused by the toxic properties of lead and cadmium, injuries associated with repeated movements, skin diseases and respiratory conditions due to the inhalation of toxic agents. The most common types of injuries are sprains, burns, cuts, lacerations and punctures. This guide is aimed at all persons working in the metal scrap recycling sector, including employers, employees, safety professionals and industrial hygienists. It can help identify and manage the hazards associated with exposure to various metals and chemicals, and with processes and equipment used in this sector. Contents: commonly recycled metals and their sources; common recycling processes; recognizing and controlling hazards. An appendix lists exposure limits for selected metals.

Effects on the human immune system of occupational exposure to metallic mercury
Einfluss gewerblicher Exposition gegenüber metallischem Quecksilber auf das menschliche Immunsystem [in German]
Mercury (Hg) concentration in blood samples taken from 12 male workers in a mercury recovery plant were compared with that from two groups of controls. The mean Hg concentration in the mercury workers' blood (9.84µg/L) was almost 6 times higher than that in the control groups. The Hg concentration in the urine of exposed workers (9 to 340µg/L) was also considerably higher than that in the control groups (around 1µg/L). However, no correlation between Hg concentration in the blood and immunological parameters could be found. The somewhat higher concentration of leucocytes and neutrophilic granulocytes in the blood of exposed workers was due to the higher percentage of smokers among the workers than among the controls (70% versus 30% and 20%). Smoking is also seen as the cause of the slightly lower percentage of T-lymphocytes in the blood of exposed workers. The somewhat lower serum IgM concentration in the exposed workers than in control group 2 is explained by the presence of women in that control group. No differences among the 3 groups were found with regard to other immunological parameters. No evidence of an effect of mercury exposure on the immune system was found.

Exposure to polybrominated dibenzofurans and dibenzodioxins in copper smelting plants and in the production of flameproofed plastics
Belastung durch polybromierte Dibenzofurane und -dioxine in Sekundärkupferhütten und bei der Herstellung flammgeschützter Kunststoffe [in German]
Exposure to polybrominated dibenzodioxins (PBDD) and dibenzofurans (PBDF) was determined at selected workplaces in two scrap metal smelting plants and three plants producing flameproofed plastics in Germany. The smelting plants were chosen because they also process copper-containing scrap with small amounts of plastics. In the plants producing flameproofed plastics, samples of flame retardants applied in flameproofing as well as samples of flameproofed plastics were analyzed for the presence of PBDD and PBDF in addition to air samples. In the air samples the concentrations of mono- to hexabromodibenzofurans ranged from 258 to 77,414pg/m3. Most of the air samples contained PBDD and PBDF with bromine at positions 2, 3, 7 and 8. None or very low concentrations of these compounds were detected in the flame retardants and in the flameproofed plastics samples as well as in all samples that were analyzed in the scrap metal smelting plants.

Study on the health hazards of scrap metal cutters
The 54 scrap metal cutters employed by a shipbreaking and foundry plant in Singapore were matched with controls (construction workers), interviewed and given medical examinations. Most were contract workers paid on a piece-work basis. No respirators were provided or worn. The workers were unaware of the potential hazards of metal fumes. Cough, rhinitis and skin burns were more prevalent among the cutters than among controls. Blood lead levels exceeded the biological threshold limit value of 70µg/100L in 10 of them. The 10 were transferred temporarily to other work and advised in respirator use. Personal sampling for airborne lead in the workplace gave levels of 0.01-0.57mg/m3 (ACGIH TLV: 0.15mg/m3); the values were correlated with the lead content of paint on the metal being cut. Plant management was advised of the need for protective equipment and periodic medical examinations.

Symptoms of exposure to o-chlorobenzylidenemalononitrile
o-Chlorobenzylidene malononitrile no bakuro ni yoru shōjō ni tsuite [in Japanese]
o-Chlorobenzylidenemalononitrile (OCMB) is a riot-control agent. Containers contaminated with the compound can be included in metal scrap. Industrial injury patients showed abnormality in smelling, nasal respiratory resistance, or other symptoms believed to be caused by exposure during work with OCMB. In 1 case (2 episodes), the subject was exposed and continued to work for more than 2 hours in spite of obvious and strong symptoms in the eyes, nose, throat and chest. Slight reddening of the nasal and laryngeal mucosae, and elevation of nasal respiratory resistance and lower airway resistance were observed. Taste was normal but olfactory sensitivity was reduced and a slight reddening of the trachea and bronchial mucosa were noted by bronchoscope. In about six months, recovery was essentially complete. In 1 case (1 episode), the subject was exposed, and stopped working immediately when symptoms appeared. In this patient, all findings were almost normal. Scrap metal workers and others who may be exposed to OCMB should always wear protective gear.

Biological monitoring of cadmium workers
This letter to the editor suggests that, when monitoring for cadmium exposure, both blood and urine cadmium levels should be measured. A long-term study of cadmium levels in the blood and urine of 2 men working with molten metal in a scrap-metal processing plant shows that sudden increases in cadmium exposure levels might only result in increases in blood cadmium concentration.

Collective occupational lead poisoning
Une intoxication professionnelle collective par le plomb. [in French]
A survey of 27 workers employed in a plant engaged in the recovery of lead revealed 12 cases of lead poisoning. The results of the biochemical examinations are commented on, and their value and limitations assessed. Stipple cell count would appear to be inadequate as a test, whereas determination of urinary δ-aminolaevulinic acid (7mg/l or higher) and urinary coproporphyrins (300µg/l or more) are considered positive tests. Attention is drawn to the inadequacy of French legislation with respect to the prevention of lead poisoning, and measures are recommended for improved supervision of exposed workers, taking into account long-term hazards.

Order of 26 April 1972 relating to the prevention of industrial accidents and occupational diseases (Scrap-metal recovery) [France]
Arrêté du 26 avril 1972 relatif aux mesures de prévention contre les accidents du travail et les maladies professionnelles (récupération des vieux métaux) [France] [in French]
The general provisions set out as a schedule to this Order replace those of the Orders of 20 September 1954 and 11 April 1956. They emphasise the statutory obligation, when sorting scrap metal and before compacting or cutting, to stockpile separately in a place designated for this purpose all war ordinance, ammunition or any easily identifiable part thereof; to mark with an identity letter any suspicious or hollow objects which are not easily identifiable (also hollow objects which cannot be opened up manually, and to open and probe these objects). All such objects shall be handled with extreme care and sent in appropriate cases to the bomb-disposal or other similar service. In selling scrap, the fact that the above statutory obligation has been complied with shall be mentioned on the invoice or delivery voucher. After sorting is completed, the material shall be inspected by a qualified person before compacting or cutting-up. A commentary on some of the above provisions is appended.
